传统上，光伏电池板的储电主要是为独立应用而设计的。相比之下，我们在本文中关注的是连接到电网的房屋，这些房屋有一个小规模的存储空间，用于存储部分太阳能，以便在一天或第二天内延迟消费。通过这种方式，房主变得不那么依赖电网，只需为他的能源生产净短缺买单。本地存储解决方案为许多新的应用铺平了道路，例如省略了线路的过电压和电力线断电的桥接时间段。自2009年以来，德国公开鼓励使用自消耗的光伏能源，这可以通过电力储存来实现。本文提出了一种确定光伏并网发电住宅最优存储容量的方法。通过在房屋中的测量，我们能够建立存储大小的计算规则。电力储存包括两种情况：-储存系统是满足大部分电力需求的最佳方案；-它是满足住宅高峰电力需求的最佳方案。在这些计算规则之后，需要第二步来确定实际电池的大小。本文论述了在购买特定电池如铅酸电池和锂离子电池之前应考虑的方面。
Classically electricity storage for PV panels is mostly designed for stand-alone applications. In contrast, we focus in this article on houses connected to the grid with a small-scale storage to store a part of the solar power for postponed consumption within the day or the next days. In this way the house owner becomes less dependent on the grid and does only pay for the net shortage of his energy production. Local storage solutions pave the way for many new applications like omitting over-voltage of the line and bridging periods of power-line black-out. Since 2009 using self-consumption of PV energy is publicly encouraged in Germany, which can be realised by electric storage. This paper develops methods to determine the optimal storage size for grid-connected dwellings with PV panels. From measurements in houses we were able to establish calculation rules for sizing the storage. Two situations for electricity storage are covered: – the storage system is an optimum to cover most of the electricity needs; – it is an optimum for covering the peak power need of a dwelling. After these calculation rules a second step is needed to determine the size of the real battery. The article treats the aspects that should be taken into consideration before buying a specific battery like lead–acid and lithium-ion batteries.
